The Eurotherm 620L02204000010UKENW0000000B0000000 enables speed control of induction motors with an encoder. It also provides for a co-processor and ports for a fibre optic communications network.
During normal operation you can monitor the device through the indicator LEDs on the control panel. Viewing the LEDs, you can see if the Eurotherm 620L02204000010UKENW0000000B0000000 is receiving electrical power and running without errors or alarm conditions, the Run signal is active and there are no errors or alarm issues, the drive is in Local or Remote mode, or if a voltage has risen above the dynamic braking threshold.
Another method to monitor the operation of the device is through the diagnostic messages. The diagnostic information is available from a menu in Remote Control mode. It lists many values that are critical to the operation of the device. The diagnostic messages display on the 2-line display on the control panel. Menus enable you to view categories of diagnostic information. For example, select the TOTAL SPD. DMD menu to view the speed loop total setpoint.
If an alarm condition occurs, a message is displayed on the 2-line display and the 620L02204000010UKENW0000000B0000000 trips or shutdown automatically. To clear an alarm message, you can press a key on the keypad. For example, if the motor temperature rises above a threshold, the device trips and the MOTOR TEMP message displays. This might happen if the motor runs too long without a cooling fan ventilating the device, or if the load is beyond the maximum. Or, if the electrical voltage is too high or too low.
